Real Housewives of Beverly Hills star Kim Richards sat down with ET's Nischelle Turner on Wednesday to discuss her struggles with sobriety and open up about the drama surrounding the Bravo reality series.

"Housewives has been wonderful for me," Richards told Turner. "I did enjoy doing it at times. We did fun things. And other days, it was just completely stressful."

Richards opened up about her relationship with her sister, Real Housewives star Kyle Richards, admitting that she believes the reality show damaged their relationship. The sisters were estranged for months following the latest season of the show, but recently spent time together at Kim’s daughter Brooke’s wedding and are now "talking."

"She came to Brooke's wedding," Kim told ET. "And that was actually the first time I had seen her in six to seven months. So that was a little hard."

Kim also opened up about her fellow Housewives, including Lisa Vanderpump, whom Richards has described as a "manipulator" in the past.

"She's witty, she's fun, she has a big heart for people she loves, but I think Lisa is ... she’s phony," Richards said. "Sometimes I felt like she was my friend, and you know, I believed her, but in a heartbeat she changes."
